The Louisville Fire Department is the third oldest all-paid staff fire department in the nation. The first fire brigades established in Louisville were in 1780, two years after the city's creation. The first firehouses in Louisville were volunteer fire departments scattered throughout the city until June 1, 1858, when the city took control and replaced the hand engines with five steam engines and volunteers with paid staff. There were initially three fire stations, 65 full-time firefighters, and 23 horses.

The Louisville Division of Fire currently operates out of 21 fire stations, located throughout the city in 4 battalions. Each battalion is commanded by a battalion chief. The 4 battalions are under the command of a citywide tour commander each shift. The Louisville Division of Fire operates 18 engine companies, 8 truck companies (including 3 quints), 2 rescue companies, 3 HazMat units, 3 fireboats, 1 ventilation unit, 5 utility mule ATVs, and numerous special, support, and reserve units.
